A printer includes a detection unit configured to detect an error, a storage unit configured to store in itself error information corresponding to the error, a communication unit configured to communicate with an external apparatus, a printing unit configured to perform printing on a printing medium, and a control unit.

A printing apparatus includes a transport unit including a roller that transports a recording sheet in a transport direction, a transport motor that rotates the roller, and a driving circuit that drives the transport motor, a head that performs printing on the recording sheet, a cutter that cuts the recording sheet, and a control unit. The control unit puts the transport motor into a hold state by the driving circuit when the recording sheet is cut by the cutter, and puts the transport motor into a short brake state by the driving circuit after the recording sheet is cut by the cutter.

Disclosed herein is a mobile printer freefall detection and protection mechanism. Printers may be subject to vibration or free fall during printing. This is more likely to happen for a mobile printer. In such cases, the printing performance will be adversely affected a lot or a thermal printhead (TPH) in the printer could be damaged. This disclosure describes a system and method of solving this problem by measuring the G-forces at using at least one sensor to determine if it is safe to start operation again.

A device includes a current sensor, a first current monitor, and a second current monitor. The current sensor is to sense a current between an input node and an output node. The first current monitor is to disconnect the input node from the output node in response to the sensed current exceeding a first threshold current for a period exceeding a threshold period. The second current monitor is to disconnect the input node from the output node in response to the sensed current exceeding a second threshold current greater than the first threshold current.

A printing apparatus includes: a printing unit configured to perform printing on a medium; a conveyance unit configured to convey the medium; a winding unit configured to wind up the medium after printing; and a prompting unit configured to prompt a user to fix a leading end of the medium to a winding core material in response to the leading end of the medium reaching a prompting position located downstream of the printing position in the printing unit.
